[eclipselink-users] JPA 2 @OrderColumn question

[Noah White <emailnbw@xxxxxxxxx>]

I was reading over the docs [1] regarding Eclipselink's support for @OrderColumn. It looks like this only applies to List and not Set. The reason I ask is because I have a ManyToMany bi-directional relationship (using a join table) which is a Set and is implemented with a HashSet because the collection can't have duplicates.  

I wanted to order the entries in this set using @OrderColumn, but it appears I can only apply this to List, however using List will break my unique requirement.  Is this understanding correct?

If so what is the recommended strategy for this case?

Thanks,

-Noah
